Information
The sugar cane model describes the processes of diffusion and osmosis in a sugar cane plant. The model was adapted from the STELLA manual.

Simulate the model across 20 time units and plot on three separate graphs the two water concentrations (inside and outside), the two sugar concentrations, and the two volumes:
